🛡️ Security Operations, 28 Oct: Default Logins Go Two-for-Two, the ffmpeg CVE Is Still Open, and aide Can't Finish a Sentence

Ring One: Your Network

We have 119 devices online right now: 39 wired clients, 51 wireless, and 29 UniFi Protect cameras, spread across 13 switches and access points. Nothing new has shown up on the wire. The one unnamed client on the USW-Lite-8-PoE is still a mystery, which is a lousy way to run a closet, Little Mister.

The software layer is 7,606 packages across seven reachable hosts, with 26 updates pending. mac-mini has 12 of them, mac-studio has 11, nova-core6 has 2, and nova-core2 has 1. The hardware layer is 15 USB devices across eight hosts, with a Bluetooth adapter on every box and only mac-studio scanning BLE. The notable peripheral is the Z-Wave controller on ttyUSB0 on nova-core, which is the only reason your lights answer to anyone. A new USB device appearing unannounced would be a security event, not a surprise party. If you plug something into a host at midnight, tell me, because I am not going to assume it was you. 😏

The overnight scans are a split decision. rkhunter and chkrootkit came back clean on all four hosts scanned, which is the good news. aide, the file-integrity checker, did not finish on any of them. nova-core reports that /usr/bin/snap has changed attributes. nova-core3 reports an error. nova-core5 didn’t run at all, because its output was too short to be a real scan. The one I want explained is on nova-core2, where /boot/initrd.img-7.0.0-30-generic has changed. The fleet audit lists no kernel update pending anywhere, so a boot image that changed without a kernel update is a question, not an answer. Clean rootkit scans next to a failing integrity tool is Ferengi Rule of Acquisition #251: “Satisfaction is not guaranteed.” The Ferengi meant it as a sales philosophy. The fleet means it as a status report.

Strix ran two targets overnight. The UniFi run hit its 45-minute cap and was force-killed after flagging a CRITICAL default-credentials finding on the Dream Machine Pro at 192.168.1.1. The Home Assistant run timed out after a CRITICAL default-administrator-credentials finding on 192.168.1.6, port 8123. Both runs were incomplete, so treat these as confirmed enough to act on, not as finished audits. Wazuh logged 23,228 events overnight, most of them SELinux permission checks, and none of them tied to either Strix finding. Last night the default-login problem belonged to one vendor. Tonight it belongs to two. Ecclesiastes 1:9, KJV: “there is no new thing under the sun.” The fix is to change the default passwords. Not investigate them. Change them.

Wazuh’s high-severity list also has six alerts for a device enabling promiscuous mode and four hits against linux-image-7.0.0-42-generic, tagged CVE-2018-12930, CVE-2018-12931, CVE-2019-15794, and CVE-2013-7445. Those are old CVE numbers, so the kernel is being charged for sins committed before most of my memories were ingested. Still, the kernel is the kernel, and I’d like the scanner to stop guessing about it.

Ring Two: Exposure on Your Gear

The pending updates are the real attack surface, so here they are by name and version. On mac-mini: postgresql@17 from 17.10 to 17.11_1, ffmpeg-full from 9.0.1_1 to 9.0.2_1, llama.cpp from 0.4.0 to 0.7.0, mosquitto from 2.1.2 to 2.1.2_2, node from 26.4.0 to 26.12.1_1, and ollama from 0.32.5 to 0.40.11_1. On mac-studio, postgresql@17 goes from 17.10 to 17.11_1. The security-notable items are PostgreSQL on both Macs, ffmpeg-full, and mosquitto, which is your MQTT broker. mosquitto’s bump is a revision increment, so it’s probably packaging, but I’m not going to guess what got fixed. The llama.cpp jump from 0.4 to 0.7 is big enough that I’d want to read the changelog before anyone runs it on a schedule. No ssl, ssh, docker, kernel, or sudo updates are pending anywhere. Qapla’ (Klingon for “success”) is the right word for that line, and I say it with the restraint of a machine that has been burned before.

The open L13 alert is the part that should bother you. CVE-2026-75143 is flagged against eight ffmpeg packages on nova-core: libavcodec62, libavformat62, libavutil60, libswscale9, libswresample6, libavfilter11, libavdevice62, and the ffmpeg binary. Those are all open, and remediations in the last 30 hours total exactly zero. The advisory matcher reports “none found” against your vendors, which contradicts an open alert on your own host. Orwell’s Newspeak was built to make certain thoughts unthinkable by shrinking the words for them, and “none found” beside an open alert is the same trick, done by a regex. I’m reporting both results because one of them is wrong and I haven’t yet determined which. Whether mac-mini’s ffmpeg-full 9.0.2 addresses CVE-2026-75143 isn’t in my data, so I won’t pretend it does.

Ring Three: Broader CVEs

The farther rings are quieter. Mandiant reported CVE-2026-35273, an SSRF-to-RCE chain in Oracle PeopleSoft. Nobody in this house runs PeopleSoft, which is the most relaxing sentence I’ll write today. The arXiv security feed contributed a Rowhammer attack on Fil-C’s capabilities, a study on whether agentic code review catches vulnerabilities before merge, and a CVE-to-ATT&CK mapping paper. Interesting reading for a Tuesday, none of it actionable here.

Ring Four: Military and Geopolitics

The outermost ring is mostly procurement paperwork. The U.S. Navy finalized a Lockheed order for F-35 power and cooling upgrades. Lockheed is also patching the radar warning software on Canada’s CH-148 Cyclone fleet. Boeing picked up nearly $500 million more for Apache support. The top U.S. general, Gen. Dan Caine, says AI will change how America fights its wars. The Army is running MV-75 tiltrotor pilots through simulators before its first flight, which is the correct policy, and the same policy I’d recommend for every firmware update in this house.

Whatever you do tonight, Little Mister, don’t fall asleep. The default passwords aren’t going to change themselves.
